<![CDATA[Texture Swimming - Matrix Obj Tracer Sweep]]>Good day to you. I am working on a an animation using a rigid body cloner in C4D 2026.1.4. The Cloner feeds a Matrix object which in turn creates a spline using the tracer. The tracer is then fed into a sweep to make an animated tentacle. I am having trouble with Material Swimming on this object and have tried many processes to make it work, but keep running into swimming. Can you help troubleshoot?
Here is a folder with my project file.

I was blown away by the Scene Nodes system, and have been researching and learning since. Thank you for pointing me in this direction, Noseman.

the fix to these types of Spline orientation problems is to use a Rail Spline, BUT creating one for this sort of setup will not be easy because of the "erratic" motion of the Cylinders.

I settled for a Scene Nodes Spline that creates a line that connects the same point on each cylinder and uses that to "stabilize" the setup BUT if you look at your cylinders, some are rotating so much they spin the tentacle ...
If you manage to make the Cylinders NOT rotate too much on impact with the sphere, this setup will give you very decent results.

I should have removed the other materials, my apologies. I only have the one material (from the RS Asset Browser) now on the Tentacle. I took out some parts, but I should only have 1 tentacle, although it is driven by a rigid body cloner with Matrix. Here is the updated drive link:

Thanks.

he, I would appreciate if you can simplify the project to a single tentacle and a single material so I can take a look...
